Receiving RequestError when using the twilio-ruby gem - ruby

Question

I am try to use the twilio-ruby gem, but got a Twilio::REST::RequestError. What does this mean? Here's the code I'm using:
Controller
Class UserController < ApplicationController
def new
#user = User.new
end
def createUser
#user = User.new(user_params)
if #user.save
render text: "Thank you! You will receive sms notification"
account_sid = '*****'
auth_token = '*****'
#client = Twilio::REST::Client.new account_sid, auth_token
##client = Twilio::REST::Client.new account_sid, auth_token
#client = Twilio::REST::Client.new(TWILIO_CONFIG['sid'], TWILIO_CONFIG['token'])
# Create and send an SMS message
#client.account.messages.create
({
:from => '+127*****',
:to => #user.phone,
:body => "Hello"
})
else
render 'new'
end
end
private
def user_params
params.require(:user).permit(:name, :email, :phone)
end
end
Why is this generating an error?

Answer 1

A RequestError means that we couldn't send the SMS message. It may mean you don't have international permissions to send to the number in question, or you are trying to use a Caller ID for a phone number that you don't own, or you're trying to send to a landline, or any number of problems.
Here is an example of how to catch a RequestError and view the attached error message.
require 'twilio-ruby'
begin
client = Twilio::REST::Client.new account_sid, auth_token
client.account.sms.messages.create(
from => from_number,
to => to_number,
body => "Hello World"
)
rescue Twilio::REST::RequestError => e
puts e.message
end
